Why don't you download SUPERAntiSpyware
? Its better than all 3 you mentioned (I own all of what you tried). Kaspersky is only better in the anti-virus department (picks more up traces) but SuperAntiSpyware does pick up the nasty original files.
Lifetime free - if u don't want it to autoupdate or autoprotect (onetime $20 lifetime license otherwise). Make sure you set it , in the Preferences, to NOT ignore file locations.
BTW all anti-malware products are set to ignore specific locations on a computer , to "speed up" the process. That is 50% of the reason why most A/V software misses a lot of stuff. They often ignore the System Restore folders (where most powerful malware reside to "reinstall" themselves - NORTON specifically ignores this location).
The other 50%? It's a crappy software !
If you doubt my opinion, get rid of Norton (download their Norton Removal Tool), keep Kaspersky and install SuperAntiSpyware FREE edition to scan after Kaspersky to see what it missed - and it will be a lot !
